The method contemplated by this invention in- Y jcludes the steps of first compressing a column of air; breaking said column into jets within a tank of treating liquid where the air is saturated; conducting the compressed disinfectant laden air to points within a mass of grain and there libergonating theV same in the form of spaced apart jets, whereby vthe interstices throughout the mass are completely filled with an effective disinfectant which acts upon substantially every grain constituting the mass. Details of construction forming a part of the treating apparatus embodyother objects of this linvention and modifications as to the method and refinements of practicing the same are possibleY without departing from the broad concepts there- One embodiment of the invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a diagrammatical .viewV of a grain bin having associated therewith treating'appay f A ratus made in accordance with this invention. Fig. 2 is an enlarged, fragmentary, vertical,

central section through the lower portiony of the air saturating tank, and,

Fig. 3 is an enlarged, vertical section through l the end of the compressed air conduit illustrating any size or shape, so long as the same is used to (il` store a mass of grain 8 therein.` The well known outlet 10 may be provided asa part of bin 6 and in the instance illustrated, it will be assumed that bin 6 is cylindrical in cross section. In storage bins of this character the grain oftentimes is lat f very high temperature. Weevils and objection- Vwhich 'is provided with a series of holes 14. These holes -14.

able insects .which multiply as'the .temperature risesare oftentimes present in the grain wheny introduced to bin `G ,and if grain 8 is left a great lengthof time, parasiticlife, such as these weevils, destroy the-:value of the grain. It is cus- Vtornary to introduce disinfectant to a bin of vgrain by pouring a quantity into bin 6 at the top thereof and directly on to the mass of grain 8. Gasifying takes place and gravity, together with the heavier-than-air characteristic of the gas, causes the liquid and gas respectively to'pass down into mass of grain 8. Where bin 6 is of any size, the grain at the top is properly treated, while the grain at the bottom practically never receives the disinfectant in either form mentioned.

`In accordance with the object of this invention, therefore, there is provided a conduit l2 which extends practically the full length of bin 6 and holes 14 are spaced apart along the length of conduit 12 where it passes through grain 8, and may be altered as to number in accordance with conditions. The lowerrnost end of conduit l2 is provided with a plug 16, having a drain opening 18 therethrough, which allows the escape of any collected liquid. VCompressed air, laden with disinfectant, is forced through holes 14 into the interstices within the mass of grain 8. y

To carry out this feature of the invention, it is necessary to provide means such as a pressure pump'20 to create a column of air under pressure. This column of air is conducted to tank 22 through pipe 24, where the same is broken into a large number of jets through the intermediacy of head 26, having perforations 28 formed therein, as i1- lustrated in Fig. 2. Tank 22` contains a liquid disinfectant of ordinary character, such as carbon bisulphide and tetrachloride, and as this liquidA is churned and agitated by the jets of air forced through perforations 28,'the air becomes 95 laden practically 'to the point of saturationwith disinfectant. This laden air then passes from` tank 22 to conduit'l2 through a connecting pipe 30 and escapes as before mentioned through 100 This method, manifestly, releases air under pressure into bin 6 and if the temperature if the Without departing from ed claims.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

1. Apparatus for disinfecting grainV comprising, in combination, a grain bin; a compressor, a tank the scope of the appendfor liquid disinfectant; a perforated head within said tank at the lowermost part thereof; a pipe establishing communication between compressor and perforated head; a verticallydisposed cen-A,

trally located length of conduit within said bin; and a series of holes formed through said con-` duit, said conduit extendinginto said bin from the top thereof` and terminating in"V spaced relation .to the bottom of said bin.

2. In apparatus for disinfecting grain, a grain bin; a compressor; a tank for liquid disinfectant;

a conduit extending downwardly into said bin from the top thereof; a pipe connecting the compressor tank and conduit to form a continuous sys-4 tem; a series of holes formed through the -side of said conduit; and a plug at the free end of said conduit, said plug having a drain opening therethrough whereby to free said conduit of disinfectant not passing therefrom through said holes.
